How many chips with 12 address buses and 4 data buses are needed for 16k memory is needed.?

if we have 10 address bits then we can have a memory module of

2^10 = 1024 b = 1kb

so for 16kb we need

16*2^10 = 2^14=16kb

here we need 2 chips as 1 chip only provid us 2^12 memory.

Address and data bus are multiplexed to reduce complexity.
